Here's how the cover to Marvel Comics X-Men #23 was made-
This is the first issue of a new arc - so different setting.
The sketches are drawn at 2x3 inches in my sketchbook in pencil and pen and then cleaned up and colored in Photoshop.
Pencils drawn in Light Blue and HB lead on 12 x 18 Bristol Board.
Inks to come...
Colors by me in Photoshop CS3 with a Cintiq 13 HD
